ʻO nā mea hoʻopaʻa ikaika kiʻekiʻe e hana i ka crispness i ka wā i hoʻopaʻa ʻia. Pono ka nānā kūikawā.
Hōʻike pinepine ʻia ka embrittlement hydrogen e ka haʻi lohi ma lalo o ke kaumaha. Aia nā pūnāwai kaʻa, nā mea holoi, nā ʻili, nā puna wai a me nā ʻāpana galvanized ʻē aʻe, i loko o kekahi mau hola ma hope o ka haki ʻana o ka hui, ʻo ka haʻihaʻi o 40% ~ 50%. I ke kaʻina hana o ka hoʻohana ʻana i nā ʻāpana cadmium-plated o kahi huahana kūikawā, aia nā ʻāpana ʻōpala, a ua hoʻoholo ʻia kahi pilikia kī kī aupuni a ua hoʻokumu ʻia kahi kaʻina dehydrogenation koʻikoʻi. Eia kekahi, aia kekahi mau hydrogen embrittlement ʻaʻole hōʻike i ka lohi ʻana o ka haki ʻana, e like me: electroplating hanger (steel wire, copper wire) ma muli o nā manawa he nui o ka electroplating a me ka pickling plating, ʻoi aku ka koʻikoʻi o ke komo ʻana o ka hydrogen, ʻike pinepine ʻia i ka hoʻohana ʻana i kahi paʻi. hiki mai ke ano hakihaki; ʻO ka mandrel o kahi pū pana, ma hope o kekahi mau manawa o ka chroming, hāʻule i ka honua a haki; ʻO kekahi mau ʻāpana kinai (ke koʻikoʻi kūloko nui) e pohā i ka wā pickling. Hoʻohana nui ʻia kēia mau ʻāpana me ka ʻole o ke koʻikoʻi o waho, ʻaʻole hiki ke hoʻohana hou ʻia e hoʻihoʻi i ka paʻakikī kumu ma o ka dehydrogenation.
ʻO ke kiʻekiʻe o ka ikaika waiwai, ʻoi aku ka nui o ka naʻau o ka hydrogen embrittlement. He manaʻo kumu kēia e pono e wehewehe ʻia e nā ʻenehana lapaʻau i ka wā e hōʻuluʻulu ai i nā kikoʻī kaʻina hana electroplating. ʻO nā kila me ka ikaika tensile σb>105kg/mm2 i koi ʻia e nā kūlana honua pono e hoʻokau ʻia i ke koʻikoʻi pre-plating a me ka mālama dehydrogenation post-plating e like me ia. Pono ka ʻoihana mokulele Farani i ka mālama dehydrogenation kūpono no nā ʻāpana kila me ka ikaika hua σs>90kg/mm2.
Ma muli o ka pilina maikaʻi ma waena o ka ikaika kila a me ka paʻakikī, ʻoi aku ka intuitive a maʻalahi hoʻi e hoʻokolokolo i ka naʻau hydrogen embrittlement o nā mea ma ka paʻakikī ma mua o ka ikaika. No ka mea, pono ke kaha ki'i huahana a me ka hana machining me ka paakiki kila. I ka electroplating, ua ʻike mākou ua hoʻomaka ka paʻakikī o ke kila a puni ka HRC38 e hōʻike i ka pilikia o ka haki ʻana o ka hydrogen embrittlement. No nā ʻāpana kiʻekiʻe aʻe ma mua o HRC43, pono e noʻonoʻo ʻia ka dehydrogenation ma hope o ke kau ʻana. Ke pili ka paʻakikī i ka HRC60, pono e hoʻokō koke ʻia ka mālama dehydrogenation ma hope o ka mālama ʻana i ka ʻili, inā ʻaʻole e haki nā ʻāpana kila i loko o kekahi mau hola.
* Hōʻike ke kiʻi ma lalo nei i nā incoterms kālepa like ʻole. E ʻoluʻolu e koho i kāu makemake.
